EPBC Threat Rating: Moderate
IUCN claim: “The reasons for past declines of the golden bandicoot are predation by feral cats and red foxes”
Cats were the main predator of a group of reintroduced, predator-inexperienced bandicoots (Blythman et al. 2020). Cats also predated on another reintroduced group (Christensen & Burrows 1995) and on locally-born bandicoots (Wysong 2016; Doherty et al. 2017). Bandicoots were last confirmed in the Nullarbor 37 years after cats arrived (Wallach et al. 202X).
Cat breached fence of semi-captive bandicoot enclosure, none were hunted in 5 weeks (from Moseby et al. 2015). Bandicoots were last confirmed in NSW 18 years before cats arrived (Wallach et al. 202X).
There are no studies linking cats to golden bandicoot populations.
The fate of reintroduced animals is not a reliable proxy for the fate of
populations. In contradiction with the claim the extirpation record from
NSW pre-dates the cat arrival record.
Evidence linking Isoodon auratus to cats. A. Systematic review of evidence for an association between Isoodon auratus and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Isoodon auratus, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance. B. Last records of extirpated populations relative to earliest local records of cats. Error bars show record uncertainty range. Predator arrival records were digitized from Abbott 2008.
